That's good advice...pick yourself up, dust yourself off and get back up on the LC wagon!
But when you say you hit a plateau, how long were you stuck? In my expereince, I can stay at the same weight for weeks without budging and then whoosh!

I think it's smart to question your program when you do plateau, but don't let it get you down. Stay the course, skip the fries and be patient. Have faith in the WOE and yourself. If you have to have snacks, make them LC. You'll be glad you did! I let lmyself think that every slip up erases a full good day's LCing. It helps keep me on course.

Good luck!
